Sustainable Ships developed an interactive shore power cost-benefit model a shipowner’s perspective
Project summary
NatPower Marine required a clear understanding of how shore power competes with onboard energy solutions over the lifetime of a vessel. The objective was to assess shore power not in isolation, but in the context of alternative fuels and hybrid configurations, taking into account emissions reduction, regulatory compliance, and long-term cost implications from a shipowner’s perspective.
Sustainable Ships developed a comparative assessment of feasible energy configurations for a hybrid merchant vessel, including methanol and biofuel blends, battery hybrid systems, and combinations with and without shore power. The analysis translated these options into cost, emissions, and regulatory outcomes, providing NatPower Marine with a data-driven basis for understanding shore power pricing and its competitiveness relative to alternative decarbonisation pathways.
Key highlights
Client was NatPower Marine, a shore power infrastructure provider
Problem was the lack of detailed knowledge on the business case for shore power from a shipowner’s perspective
Ship types considered were RoRo Ships, Container Ships and General Cargo Ships
Client review
“We are satisfied with the project deliverables. Sustainable Ships supported us in developing a practical techno-economic model to assess shore power business cases across different vessel types, routes, and ports. The team was responsive and collaborative throughout, iterating quickly based on feedback and validating key assumptions. Overall, Sustainable Ships provided a strong mix of regulatory expertise and hands-on modelling capability that accelerated our own development work and internal software tools.”
